Real-time performance monitoring of coal-fired power plants is becoming very important due to the impending deregulation of the electric power industry. Performance testing is made to be real-time by changing the traditional output loss method to include an estimation of coal composition based on the Continuous Emission Monitoring System (CEMS) data. This paper illustrates the robustness of the calculations by introducing a variance into each of the calculation inputs to access its effect on the final outputs of heatrate, boiler efficiency and coal flow. Though the original study was over five power plants this paper presents results for the two most diverse coals.

Integrated Gasification Combined Cycle (IGCC) utilizing solid and unconventional liquid fuels has now reached commercial stage as evidenced by their world wide construction and successful operation. The proposed ASME Performance Test Code 47 (PTC47) provides the users and owners of these new power plants, the guidance and procedures on conducting a performance test and evaluate the deviation from the performance guarantees. This paper reports the use of PTC47 codes in evaluating the test correction factors for the Wabash River IGCC Power Plant.
